"111 Faces" is a series of 111 real physical portrait paintings by the Berlin based artist Sebastian Bieniek (B1EN1EK) painted 2016-2013. The concept of all BIENIEK NFTs is to use the blockchain as the best possible tool "for a provenience" of real physical artwork. The physical painting is in this case signed, the NFT not.
